Some orchids are known to have a very specialized suite of floral adaptations that favor certain pollinators while precluding others. Such adaptations can prevent cross pollination (fertilization by pollen from a different species), or minimize the amount of energy devoted to the production of nectar and/or pollen. This orchid strategy can be best described as:

Explanation:

The orchid strategy can be best described as Postzygotic

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
